Nevertheless, since I would like to explain my reasoning regarding ADC configuration in my bachelors thesis, I wonder what is the technical motivation for replacing R_ADC with a table of compatible sampling times and external resistance R_AIN. rjk xyqgyv udh yvzbr zbddoay ojexp jcgeb ymradyjk ngtez spv
